Investigation of the genetic diversity of domestic Capra hircus breeds reared within an early goat domestication area in Iran

Background: Iran is an area of particular interest for investigating goat diversity. Archaeological remains indicate early goat domestication (about 10 000 years ago) in the Iranian Zagros Mountains as well as in the high Euphrates valley and southeastern Anatolia. In addition, mitochondrial DNA data of domestic goats and wild ancestors (C. aegagrusor bezoar) suggest a pre-domestication management of wild populations in southern Zagros and central Iranian Plateau. In this study genetic diversity was assessed in seven Iranian native goat breeds, namely Markhoz, Najdi, Taleshi, Khalkhali, Naini, native Abadeh and Turki-Ghashghaei. A total of 317 animals were characterized using 14 microsatellite loci. Two Pakistani goat populations, Pahari and Teddy, were genotyped for comparison.Results: Iranian goats possess a remarkable genetic diversity (average expected heterozygosity of 0.671 across loci, 10.7 alleles per locus) mainly accounted for by the within-breed component (G(ST) = 5.9%). Positive and highly significant F-IS values in the Naini, Turki-Ghashghaei, Abadeh and Markhoz breeds indicate some level of inbreeding in these populations. Multivariate analyses cluster Iranian goats into northern, central and western groups, with the western breeds relatively distinct from the others. Pakistani breeds show some relationship with Iranian populations, even if their position is not consistent across analyses. Gene flow was higher within regions (west, north, central) compared to between regions but particularly low between the western and the other two regions, probably due to the isolating topography of the Zagros mountain range. The Turki-Ghashghaei, Najdi and Abadeh breeds are reared in geographic areas where mtDNA provided evidence of early domestication. These breeds are highly variable, located on basal short branches in the neighbor-joining tree, close to the origin of the principal component analysis plot and, although highly admixed, they are quite distinct from those reared on the western side of the Zagros mountain range.Conclusions: These observations call for further investigation of the nuclear DNA diversity of these breeds within a much wider geographic context to confirm or re-discuss the current hypothesis (based on maternal lineage data) of an almost exclusive contribution of the eastern Anatolian bezoar to the domestic goat gene pool.

Estudos sobre o subdesenvolvimento capitalista: as teorias de Paul A. Baran, Andre G. Frank e Ruy M. Marini

The underdevelopment is a high relevance subject in researches and studies for the general social sciences. In this monographic paper, the marxist analysis perspective of the phenomenon approached is considerate of great importance to make a deep overlook, historical and structural, about the origins and solutions possibilities for the issues caused by it over several countries. Has been done here a theoretical analysis of three studious marxist authors of the subject: Paul A. Baran, Andre G. Frank and Ruy M. Marini. How they thought underdevelopment? Which were their scientific contributions to this theme? The main goal of this paper is to do a comparative analysis of these authors, synthesize their considerations about the underdevelopment issues and organized a theoretical and conceptual framework for a better understanding of the matters in capitalist development/underdevelopment relationship. To accomplish that, we elected four variables that supports this comparative exercises, they are: the origins, the causes, the consequences and the way-out of the underdevelopment conditions. This monographic work was made through studies of some principals books and articles of the cited authors as well as the reading of others authors that commented their theories and concepts. The considerations about the underdevelopment vitality under a world capitalist logical, rescues the debate on the transformation of this entire society project for another, been this movement the only way possible to reverse the path of the world people’s history and the major part of humankind that still lives into the “necessity kingdom”
